- Application and September 21,1892. Serial- No. 446,373. on t an To an; whom it may concern: Be itknownthat I,'-WIL IAM H. DAYTON, a citizen of. the United States, residing at Tor- .rington,"in the county of Litchfield and State *5 ofConnect-icnt,-have i'nvented'an Improve-'- ine'n't .1 in .Machinery for Swaging Wire and other Round Articles,"of which the following is a specification.- v p This invention is especially intended for t: the swa'ging of wire in. the manufacture. of

spokes for'wheels, but is available in the .inan-ufacture of other round articles and es ,pecially those that can be made frbm a continuous vvire. By the present improvement machine andsubjected to the swaging operation, and it is drawn along through the swaging dies as the proper reduction is accomplislied' and one or more complete articles are 26 thus swageda fter which the articles are cut off; successively and delivered from-the ma'- chine: I .In carrying out this invention any suitable i swagin-g apparatus-.nia'ybe made use of,.such 255- fbr instance as that represented iI1 Ll3t 6lS, 'PatentNo. 474,54S, granted to me May 189i, and the wire as fed i ltO'. the machine is preferably passed through straightener and. y the longitudinal .niovement is given to the o 'wire by pinchers that grasp the partially or along together with the wire that is being ary p'osition'while the pinchers are opened and returnedto the point of beginning to take [a fresh hold, and the completed article is out off and drops away fIOllltl'lG machine. In thedrawings-Figure l is a'p lan view of the machine. Fig. 2 is a side elevation. Fig. 40 3'is an elevation from the opposite side to 2 andwith the swa'gingmechanism and base in section and part of the pincher actuati'ng devices removed. Fig.4 is an elevation at: the opposite-side tol igz. 2, and Figs...

ingthe pinchers and for holding and cutting the wire. 3 a Any suitable swaging mechanism maybe made use of for acting uponfthe wire, rod or other article. I have represented devices similar to. those shown in my aforesaid pat em No. 474,548, that is a 'say, the dies A'B are in a cross mortisein the revolving head .0

of the actuating shaft Diand these parts are within and sustained by thesliell E, and there is a circular range of rolls F Within the. shell' E and there are die blocks Il' inline with the dips 'A' l3, and the wedges I vI are between the dies'and die blocks and they are held and "connected in any suitable inannersuchlasco by the head or pins M 'vvi th the adj listing tube S so that by an endwise. movement given tov this adjusting tube S the wedges act to cause the dies A 13 to come. closer together or.far'-.

iher apart' in the swaging operation, allot' which is. more fully described in the arm-e said patent. e

' The shell Eis s'upportedon a suitable standard E uponja bed orbase fir, preferably in the form of a pan for catching oil, and the -yoactuating shaft D isrotated by suitable means such as a-belt to the pulleyJ, 'and the ade 'nstin tube S receivesits endwise movement in any suitable manner, suchfor instance as by the mechanism hereinafter set fo'rtli.

The frame K extends out from the shell E a l and the cross shafts N and. O are supported by suitable hearings in the respective parts, v

and these shafts N and 0 receive their mo- 'tion from the countershaft P, wornrpinions 8o 2 and/3 and gear wheels 4 and 5 and the driving pulley Q can be driven continuously by a belt and either connected. to or disconnected from the coun'tershaft P by a clutch, the

parts being actuated by asui able leversucli 8 5 as that shown at 6'; and it is to be understood that the parts are so proportioned and the cams upon the respective shafts N and CS0 shapedflhat one complete movement of themachine is eifeoted by the entire" revolution of the saidshafts Njand O, and-the relative. speed of these shafts N and. O to the speed of the revolving head 0 and shaftD is such that the swaging dies'will be opened and closed the requiredn-nmber of times to perform--the 5 swaging operation dnringvthe movements of I "the machine.

The'wire lee-rod; or other article to vbe swagedis fed into the rear end of the tube S, and it is preferablysubjected to'a straighten- IOQ ing operation by a revolving or other straight ener, inflorder that such wire in passing through the tube S may not be subjected to 7 described, to holdthe wire against the plate 7 duringt he return movement of the pinc'hers and while the wire is being cut off. A convenient device for actuating this clamplever I 9 is the lever 11, connecting rod 12 and a cam 13 on the shaft 0, a portion of the surface of which is segmental and acts to hold the wire by the lever 11-, and then to release the same as the swaging operation begins.

To give an endwise motion to the adjusting tube S I prefer touse lock nuts on the projecting back end of such tube, and a fork 14 having a pivotal handle withina socket at one end of the lever R, which lever is pivoted at 15 upon the frame of the machine, and 'it is provided with an arm-16 to a cam 17 on the shaft 0, so that by properly shaping this cam the adjusting-"tube S will be moved endwise .at-the propeiytimefiand either open or close the dies A B more or less or allow such dies. to remain open without performing any swaging operation. Usually a spring 42 will be required for this lever 16 to draw it toward the cam 17.;

jUponthe cross shaft'O is a cam 18, see Fig. 3, which carn' acts" against the roller 19 of the lever U pivoted at 20, and the connecting rod 21 extends to the radius-bar V the lower end of which is pivoteda'nd, the upper end connected with the pinchers, as; hereinafter described, so as to give-inotionto such pinc'hers and carry the wire through the-machine by a longitudinalmovementgiven to such pinchers, and the connection-22 between the rod 21 and the radius barniay be raisedor low.-

- cred so that'the leverage is changed and the wire which is drawn alongby to the extent of the rednctiorn,

distance which the 1 pinchers in travel varied withoutflrequiri cam 18 and I-remark-that th" be a progressive volute or spi 6 caused .to

the pinche'rs ni'ay be .actedfiupon larity by the swaging dieg o this cam may be varied ac'zcording' t acter of the article that l s'to he rodu' as to un fy the swaging operation-ace for the base K of the ,pinch ers L,and these pinchers areof suitable construction, prefer-f" ahlywith thelower jaw 23 stationary'and'the' upper jaw 24 movabie,-and the same maybe opened by-springs 25 when not otherwise acted upon, and thereare side frames I-.l! upon the base K that receive the pivoted rocker to be closed upon {the wire for the opcrati 26 between which and the upper jaw 24 of the pinehers is a toggle block 27, and the rocker 26 has an arm or lever 28* at one side with a roller at its outer end in. the'channel bar 29, so that when this channel bar29 is raisedthe rocker is moved and the pinchers closed and firmly he d upon the wire, and

when the channel bar-is drawn. down, the

parts assume the position represented in Fig.

8, and the pinchers are opened by the springs 25 so as torelease the hold upon the wine.

I have shown a spring 30 to draw down the channel bar, and a cam 31 to act upon the lower end of the vertical member 82 of the channel bar, which vertical member is fitted in suitable slide ways upon the frame K, and the shape of the cam 31 is such that it raises the.

screw passing through the pivoted block 33 that is connected b'ystandards with the under side of the base K,', so that the pinchers can be moved backward and forward by the action" of the radius bar, connections and lever, and

I have shown a spring 34 for giving man-0H0 the leverUin one direction to keep the roiier of such lever against the cam liand to move the lever V and its connected parts.

far described, when employed in making wire spokes for wheels, is as follows:-The wire is passed through the swaging dies when the latter are open, and also through thepinchers sufficiently for such pi'nchers to grasp the same when closed, the swaging mechanism and other parts being in motion, and the wedges I, are

moved en'dwise to bring the swaging dies towardeaeh other and reduce the wire'down to the propersize for the spoke, and at-the same time the'pinchers are moved along by the action of the cam 18 the proper'extent to draw the wire along, and if the body'of the spoke is who par'allelthe wedges remain in the position to which they have been moved during the commencement of the swaging operation swaging'operation,and when the necessary 'length; has been swaged the wedges I are f v moved end-wise, so as 'to-zallow the swaging Y dies-toopenj niore or less; gradually, andthey" may open so-as. not toact upon the wire, or *t 1e;

Upon the'topof the fraineKaresl'idefway j swagi gperation-fto he performed upon the ay-open .sufiicient'ly far for a slight connec th'ein from? moved backito the oint of beginning re l The operation of the respective parts thus and the pinchers draw the wire through the swaging dies at the proper speed during the W11 here such wir'e'is leftsulllciently large 1 to l'e-ends'ofv thespdkes. The clamp in l v snow bro ught into action to hold thewir fandgthe pinchers are opened to dis the wire, .and theyare -.to lie-repeated. These swagi ngoperations may be performed and the wire may be cut oft byhand in tlie properlengths for. each spoke, the wire being separated where it is left-the largest in order that theenclsof the spokesmayhesufih ciently strong for receiving the screw threads orother" devices by which such ends are to be connected in the wheel; .Ihowever prefer to out ed the spokes automatically, and with this object in view the cutter plate is provide'd upon which is pivoted a cutterdr Prefer I ably there is a hole through both thecutter plate andthe cutter and the separation is per- ..formed bye. motion given to the cutter. This cutter plate a may be stationary in-cases where the lengths of the spokes or other articles are suchthat the cutter will not interfere-with the movement of the pinohers, but usually it. 'is preferable to allow the cutter .plate' 0 to slide'i'n the ways upon the frame K,such cutter plate being moved forward by the base K acting against the same, and the cutter plate isdrawn back by the rod 6 which is pivoted .atone end to the frame L and is screw threaded and provided with nuts, and such rod e passes freely through a holein the cutter plate, hence when the pinchers are closed and are drawing the wire along, the pinchers and cutter plate can move together, and when the cams are shaped in such a manner that the pinchers remain stationary while the cutting operation is being performed.

A convenient device for actuating the cutcam f upon the shaft N comes into action against the roller g.upon the swinging frame hthat is pivoted at z and connected'byalink the cutter can slide backward and forward upon the wire, and the parts are so timed that.

the cam f comes into. action to separate the nuts upon the rod 6 an adjustment can'be ef-' ifected, so that the wire will be separated at exactly the desired place; and I provide an adjustable stop 40 to arrest the-movement of the cutter'so that the inertia may not displace the same. This stop 40 is adjustably fastened to oneof the slides that support the cutter and it comes into contact with the stationary'bed or frame K; and it is advanta geous-to provide a pan in frontof the cutter and between the slides, as at 41, into which. the spoke as it is separated from the stock may fall. j p

I find it advantageous. to have the cutter separate from the pinchers and to construct the pinchers and the actuating devices as because with comparatively light pinchers and actuating parts, there is a small spring or yield that lessens-the risk ot' the swaging .dies by. their gripping and revolving action loosening'thehold of the spoke or wire in the pinchers. t By the foregoing, description of this appa-.

lightlas consistent with the proper strbngth,

ratus as adapted tothe vniianufacture of wire I spokes, it is notto be understood that theimprovement is limited'inzthis particular, but

that the device's maybe employed for swag. ing other articles,-and the swa'ging action may be either con ti-n uousor intermittent.

I have described the present improvements in connection with a revolv'ing swaging de'-' vice, but it will" lie-apparent that incases where the-device that is being manufactured isnot circulgiu', the lmprovements are. available with any character of swaging device.

whether it revolves so as to act all around the circular article, or whether it may remain sta- I .tionary and only-act at opposite sides of thearticlebeing swaged.' The cam-J18 being a vprogressiveincline or scroll gives motion to that the pinchers .will receive a greater or less i thepinchers through the intermediate lever movement during the time that the swaging operation is progressing, and this adapts the machine to different lengtlisof spoke, and upon this cam 18 is a movable toe 0 attached by a bolt in aslot, and adjusted by the screw roo- 43, which toe can be set to' projectniore o r less at the end portion of the scroll of the-cam, 1 and this toe is to come into action after the dies have been opened, so that the wire may *be' moved along the desired distance between ter dis represented in Fig. 2, in which the one swaging operation and the next to give the amount of material or stock necessary for spokcswill' be increased, or the reverse when 1 gthetoeis set inwardly. wire while the latter is quiescenh-andbythei Any suitableadjustable lever connections tween the swaging dies and a holding clamp,
